Does anyone fancy boarding a plane that was involved in two deadly air disasters during a raging global pandemic? Well, then there’s good news—after a 20-month grounding, the U.S. Federal Aviation Administration has given Boeing permission to to fly its 737 MAX jet again. According to Reuters, the FAA gave its approval Wednesday alongside a list of required software upgrades and training changes Boeing must make before the jets can resume commercial flights. The 737 MAX crashes in Indonesia and Ethiopia killed a total of 346 people within five months between 2018 and 2019. In both disasters, a stall-prevention system repeatedly shoved down the jet’s nose as pilots struggled to regain control.
